BUTTON-MAKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 567,102, dated September 1, 1896.

Application filed September 4, 1894. SerialNo. 522,148. (No model.)

T0 (0 whom it may concern.-

Be it known that I, FRANK J. KASPAR, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain useful Improvements in Button Making Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention has relation to a new and novel improvement in button-making machines, the object being to provide a device by means of which the operation of facing.

buttons shall be expedited and by means of which the button can be dished and faced with one operation.

In the accompanying drawings, Figure 1 shows a side elevation of a machine embodying my invention, while Fig. 2 is a front view thereof. Fig. 3 is a top View of the same.

The aim of my invention is to provide a means whereby the button shall be more promptly manufactured, and also to provide a means whereby the tools shall be made to last longer. This last feature is one'of great importance, as the tools are in the shape of cutting-dies, which are not easy to sharpen, so that it is important to keep them in working condition as long as possible.

In the accompanying drawings, A represents a suitable standard, to which the ordinary speed-spindle B, provided with a suitable stock, is secured, as is usual in devices of this kind. The speed-pulleys B are in belt connection with any suitable driving power and impart a rotary motion to the main shaft a, which shaft is providedin front with a button-chuck a. Extending from the forward portion of the spindle-frame B is an upwardly-extending arm B which is provided with a rectangular spring-actuated lever 0, connected by means of the pin 1 to said arm B At its rear end this arm 0 is provided with an ordinary coil-spring 3, secured above to a suitable support, while below this arm is provided with a treadle 4, connected by means of the rod 5 to the arm 0. The spindle-frame B is further provided with an outwardly-extending screw-stop 6, as shown .in Fig. 1. Mounted upon the button-chuck a is an ordinary locking-collar c', which is adapted, in sliding forward, to bring the chuck together and so securely clasp the button-blank. This sliding collar is actuated by means of a downwardly-extending collar 7 of the operating-lever O, as is clearly'illustrated in Fig. 1. Mounted adjoining the spindleframe B is an ordinary slide-rest D, suitably secured to the standard A, and within which the slide D is movably held. This slide D is provided at the rear with a shaft and pulley 6, within a suitable standard 8, the pulley of which is in belt connection 9 with a suitable overhead speed-pulley, so that motion is imparted to this shaft and pulley e. In front this shaft 6 is provided with an ordinary chuck 10, within the forward end of which is adjustably secured a suitable headed emerystick oc'of a suitable conformation, as shown more clearly in Fig. 3. This shaft-standard 8 is secured to the slide D proper, which slide is provided with an ordinary operating-handle 12, as shown in the figures. Mounted in front of the emery-chuck 10,and adjoining thesame, is a chisel-chuck E, which is vertically adjustable within the forward standard 13, which standard is also secured to the slide- .rest D. Secured within this chuck E is a chisel 15, which chisel conforms to the outline and style to be imparted to the buttonblank within the chuck a. The slide K is further provided with a ClOVDlVEtI'dlYrGXtQIlding hub H, which hub slides within the stock D, so that the slide-holder K, which movably contains the slide-rest D proper, can be given radial adjustment. The movable slide D is provided in front with a set-screw 20, which is adapted to abut against the slide-holder K, as will be noticed by referring to Fig. 3. These instrumentalities comprise my improved but ton-machine.

The operation of my device would be asfollows: The button-blanks to be dished and faced, and which may be of any suitable material, are placed within the chuck a, when the operator depresses the lever G by means of the treadle 4:, tightly impinging the button-' blank within the chuck a. The spindle B is in the meantime revolving at a suitable speed and is carrying the button-blank around. The chuck D is so arranged that the stem 7 in no way interferes with the revolution of this chuck, it simply controlling itin a horizontal plane. The button-blank is, of course, simply regular in outline. The first step to be taken is to bring the slide D forward until it is checked by means of the stop M, which collides in the rear with the slideholder K, in which positionithe headed emerystick :0 is adjusted to come immediately in the center of the button. The slide-holder K, as well as the-slide D, is then carried toward the chuck until the rapidly-revolving emery-head grinds into. the button-blank and forms a suitable dish, which dished portion later accommodates the buttonholes proper. The circular movement laterally is controlled by means of the screw-stop 6, which prevents the stick from working too deep into the button-blank. This stop 6 is employed in determining the depth of the dish within the button. As soon as the button has been properly dished the slide D is again carried radially outward and backward until the stop 20 engages the slide-holder K, when the chisel 15 is supposed to be in proper position for facing the button, and the slide D is again carried radially inward until this chisel engages the button-blank and imparts the proper outline until it engages the stop 6 for the second time in the operation of making one button. The slide is then carried away, the foot is removed, when the button is permitted to drop out of its chuck. This operation is, of course, repeat-ed any number of times.

Now having thus described my said invention, what Iclaim as new, and desire to secure by United States Letters Patent, is

1. In a button-making machine, the combination with a suitable revolving buttonchuck adapted to reinovably contain a button-blank, of a slide adj ustably held in front of said button-chuck and provided with a grinding-tool at one end, adapted to dish the button and a facing-tool adjustably held at the other end of said slide, said slide being revolubly held within a suitable stand and adj ustably within a horizontal plane, all substantially as and for the purpose set forth.

2. In a button-making machine, the combination with a suitable chuck adapted to removably contain a suitable button-blank, of a slide positioned in front of said buttonchuck provided with a dishing-tool at one end and a facing-tool at the other, said slide being pivotallyheld in a horizontal plane and permitted a sliding movement in a horizontal plane, and further being provided with a grinding-tool at one end and a facing-tool at the other end, so positioned that one of said tools shall be in front of the chuck at one of its extreme positions and the remaining tool in front of the chuck when said slide is in its other extreme position, all arranged substan tially as and for the purpose set forth.

3. In a button-making machine, the combination with a suitable button-chuck adapted to removably contain a suitable buttonblank, said chuck being actuated by means of a treadle-operated spring-arm to hold or re lease said button-blank, in combination with the slide, D, movably held within the holder, K, said holder, K, being revolubly held within a stock, D, said slide, D, being provided with the stops, M, and 20, checking the movement of said slide at each end, said slide, D, being further provided with the revolving grinding-tool, 00, held within the supports, 8, 8, and the facing-tool, 15, held within the holder, E, said holder and slides being adjustable, all substantially as and for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
